Bottom sediments consist of a land-derived band in the nearshore and an offshore mud dominated by foraminiferal tests. ❋ Unknown (2009)
Here we establish the chronology of high and low latitude climate change at the last glacial termination by 14C dating benthic and planktonic foraminiferal stable isotope and Mg/Ca records from a marine core collected in the western tropical Pacific. ❋ Unknown (2007)
Our reconstruction is based on radiocarbon-dated records of diatom-based sea surface temperature and sea-ice proxies and planktic foraminiferal stable isotopes. ❋ Unknown (2007)
The relatively large range in the reproducibility of foraminiferal analysis is primarily due to relatively poor intralaboratory repeatability (about ±1–2 degC) and a bias (about 1deg C) due to the application of different cleaning methods by different laboratories. ❋ Unknown (2006)
Michele Caron spent weeks behind the microscope to find just a few examples that might be a badly preserved foraminiferal shell, and in one case she may be right. ❋ Unknown (2006)
There are plenty of ice cores, foraminiferal core-counts, organic carbon assessmenets, alkanone sea temperature reconstructions and other data that tell us something about climate status and climate swings in the past, relative to now. ❋ Unknown (2006)
I think that the Vostok record may have been matched to the SPECMAP deep sea d18-O record, itself a stacked foraminiferal record and slightly tuned to orbital parameters. ❋ Unknown (2006)
Dave, The isotope composition of foraminiferal exoskeletons is controlled by that of the dissolved inorganic carbon in sea water. ❋ Unknown (2006)
Since we know that fossils are created when bone and exoskeletons primarily calcium are replaced by other minerals over long and shorter time periods, how can we tell anything from foraminiferal fossils MG/CA ratios after being buried for so long in ocean sediment. ❋ Unknown (2006)
In contrast, Moberg et al followed by Juckes et al simply grabbed a foraminiferal series that had never been calibrated to temperature – with highly non-normal distributions and inserted it by brute force in small subset composites. ❋ Unknown (2006)
Planktonic foraminiferal Mg/Ca and d18O derived sea surface temperature and salinity records from the Makassar Strait, Indonesia, show a long-term cooling and freshening trend, as well as considerable centennial-scale variability during the last millennium. ❋ Unknown (2006)
Caron, a renowned foraminiferal specialist, the thin sections I had made from that critical interval from impact to post-impact rocks for further analysis. ❋ Unknown (2006)
Assessing the reliability of magnesium in foraminiferal calcite as a proxy of water mass temperature. ❋ Unknown (2006)
Several studies have shown that foraminiferal Mg/Ca ratios systematically decrease through post-depositional dissolution under the influence of undersaturated bottom-waters or pore-waters Fig. ❋ Unknown (2006)
As I am sure most people in this discussion are aware, it is theoretically possible to reconstruct SSTs using foraminiferal abundance data alone through the use of transfer functions, modern analogue techniques, etc. e.g. ❋ Unknown (2006)
We will then use this system to carry out the first culture-based calibration of the benthic foraminiferal magnesium/calcium Mg/Ca thermometer. ❋ Unknown (2006)
Michele believes there are a few very badly preserved foraminiferal forms in there deteriorated way beyond recognition at generic or species level and I still have my doubts. ❋ Unknown (2006)
Along with minor oscillations there were laid in the interior sea various formations of sandstones, shales, and limestones, and from Kansas to South Dakota beds of white chalk show that the clear, warm waters swarmed at times with foraminiferal life whose disintegrating microscopic shells accumulated in this rare deposit. ❋ William Harmon Norton (1900)
Such shoals may be produced when volcanic islands are leveled by waves and ocean currents, and when submarine plateaus, ridges, and peaks are built up by various organic agencies, such as molluscous and foraminiferal shell deposits. ❋ William Harmon Norton (1900)
